Love the material, soft to the touch and a nice amount of stretch but thick enough to not hug baby’s chubby rolls haha! Exchanging sizes was easy and greatly appreciated, baby is currently 8 months old, 25 lbs, and wearing the 18-24 month size with cuffs rolled, and will be able to wear this unrolled through the colder months. Even though he is very chunky it’s easy to get on and off. So happy I decided to invest in quality long term wear from a Canadian small business who puts thought into their product.
